Answer:
also tripled, factor of 3
Explanation:
equation of momentum is p = m * v , where p=momentum, m=mass, and v=velocity
if m is unchanged
p1 = m1 *v1
p2 = m2 *v2
m1 = m2 and v2 = 3*v1
p2 = m1 * 3v1 = 3*p1, tripled momentum
Lever: a bar used to move something
Wedge: a tool used to go in between object to put them in place
Incline plane : a ramp it’s used to help rise heavy things
Pulley: it’s a wheel that supports movement and change of direction
Answer:
Explanation:
If E₀ is the electric field outside the smaller sphere and r is the radius of larger sphere.
E₀ = kQ/r²
The radius of the larger sphere is 3r and the charge on both sphere is same then the electric field outside the larger sphere is given as
E = kQ/(3r)² = kQ/9r² = 1/9 (kQ/r²)= 1/9 x E₀
hence the correct option is e.
